terminate the RUN command. If 00-02=0, user can press Reset key; if 00-02=1, terminate the RUN
command of digital input terminal to reach the effect of Reset. Then PLC can be restored to give RUN
command.
Note: It is recommended that the rated current of compressor is required to be lower than that of inverter.

The inverter with built-in PID controller and simple programmable logic controller (PLC) is widely applied to
water supply industry. 1 to 8 pump card, mainly applied to the situation of water supply of constant
pressure, dispenses the inverter from the need of an external controller.
The inverter provides the power supply of variable frequency for pump to implement the continuously
variable transmission (CRT) and makes the water pressure being satbly controlled via the built-in PID
controller.
There are two basic operation modes in 1 to 8 pump card:
Fixed modes of inverter pump:
Pump drived by the inverter is fixed to 1 set and maximum to 8 sets.
